5 Claims. (Cl. 177--311) 1 r This invention pertains to automobile lubrication check charts.

One of the objects of this'invention is to provide a large wall board chartwhich will clearly display a diagram simulating an automobile chassis with electric lightspositioned at signifi- 1 cant points thereon which indicate points to be lubricated, and with switches conveniently located at the bottom of the chart board, having indicia the same as the several lubrication .point lamps, connected therewith by broad visible bands or stripes, and operative to light or extinguish the lights on the chassis, as desired by Another object is to provide a check board,

as above described, which can beeasily, cheaply, and safely built and operated and provided with switches controlled b knobs conveniently. positioned on the board which may be maintained by an operator lubricating a car even with greasy hands, and with main control switches which n will light the entire group of lights on the'outline f of the chassis .or certain special groups thereof; optionally, as desired;

Another object is to provide an electrical switching arrangement for the lights on said chart board whereby, after a lubrication job has been completed and the lights turnedoffflas the various points are lubricated, the entire bank of lights may berelighted and readied for a new job by merely resetting the master switches without the necessity of resetting the switches controlling the individual lubricating point lamps;

Still another object is to provide lamps of different colors to indicate and distinguish lubrication points requiringlubrication at diii'erent intervals;

A general object is to provide a chart as above mentioned which may be installed on thewall of a garage lubrication stall so as to clearly indicate to the customer and the operator, as Well, the nature and extentof the lubrication job required and its progress as the work is performed.

Other objects will appear hereinafter.

I attain the foregoin objects 'by meansof, the

devices, construction, and arrangement of parts illustrated in the accompanying drawings ,in which- Figure l, is a front elevational View of the chart board; and

Figure 2 is the electrical wiring diagram of the circuits, switches and lamps used on said.

chart.

In the drawing, 2 indicates the board onwhich; the chart 3 is printed. On the chart a figure 4,.

simulating a plan view of an automobile; chassisis painted. Along the bottom portion of theboard is a'rail 5 on which a number of lubricating points indicating switches I through l-8 are located. 1

These switches are designated by numeralsor other indicia to correspond with lights 8 set-in. socketson'board 2 at'positions on chassis figure 4, which, in turn indicate corresponding oil-- ing or greasing points on. the chassis of a car to be lubricated.

The background of chart 4 is preferably painted white, the chassis figure thereon may then be painted black. From each light,, .set, or group of lights on the chassis figure broad bands or strips may then be painted leading directly to the switch controlling these lights. Thus, for

' example, the switch marked 2 on the left of the board is connected by band or stripe B-tolights 2 indicating lubricating points on the steering gear knuckles. This same system of marking follows through from the front of the chassis figure 4 to the rear.

Referring to the electrical diagram, Figure 2', it is noted that each of switches I is of the single pole double throw type. The pole contact'of each switch is connected by a lead l2 to one terminal of the socket or sockets of each significant light or light group indicating a lubricating point. The other socket terminal of each light is connected to a common ground lead l4 which, in turn, is connected to terminal l3 of "the secondary of stepdown transformer I5.

The two pole contact terminals of each of these switches lead to busses l5 and ii, respectively, except the pole contacts of switches 3 and p 89 are similarly connected through switch 20 to this same transformer terminal. The primary of transformer is is connected through fuse 25 and main switch 2| to the alternating current supply lines.

The globes of all lamps controlled by switches I through I2 and I4, I! and I8 are colored red to indicate that the lubrication points indicated by these are to be lubricated each 1000 miles.

The globes of the lamps controlled by switches l3 and I5 are preferably colored amber to indicate that they are special lubricating points, and are to be lubricated only on automobiles requiring universal joint and spring leaf lubrication.

The globes of lamps controlled by switches 3 and I6 are preferably colored green, for contrast. These indicate wheel bearing lubrication points and are used only on jobs where this type of lubrication is necessary.

All of the switches I through [8 except 3 and I6 are energized by job set switch H! which may be termed the 1000 mile switch. Switches 3 and I6 are energized by job set switch which may be termed the 10,000 mile switch.

It is to be noted that, as shown, all switches I through l8 except 3 and [6 are positioned so that the pole is in contact with the switch terminal leading to buss l6, and job switch 19 is likewise connected to this buss. Therefore all lamps on the chassis diagram except 3 and 6 are illuminated. However, lamps 3 and it are also shown as illuminated by the setting of switch 253 which connects the transformer terminal 23 to buss l8. 7

In use, as each lubrication job or operation is completed the operator throws each switch-i through l3--to the terminal connected to the unenergized buss, ll. The same is true of switches 3 and I6 which are thrown to buss it as the operations indicated are completed. Whereas, at the start of each job, all lamps are lit, as indicated in Figure 2, upon completion of each lubricating job the chart is dark, so far as operation lamps are concerned, and all the switch poles are connected to unenergized busses.

-When a new job is started, however, switch I9 is thrown to the right and connects the transformer terminal 23 to buss ll. This illuminates all these corresponding indicatin lamps. If a 10,000 mile job is desired, switch as is likewise operated. Therefore, to reset the indicating lights only one operation of the reset switch l9 and/or 20 is required.

Reminder lamps colored red, 3!, colored amber, and 32, colored green, are positioned in the approximate middle of the chart and connected directly to transformer. These serve to indicate when main power switch 2! i closed, and also to remind the operator of the significance of the colors of the operation lamps.

From the foregoing it will be seen that I have provided a check chart which is easy to use, foolproof, and on which all operations are clearly indicated. By using six volts, E. M. F. from stepdown transformer Hi all connections are easily made, insulation is minimized, the entire wiring system is safe from fire hazard, and the operator need not risk chance of shock in operating the switches. While the switches have been described as the single pole double throw type it is to be understood that their mechanism may include the push-pull type, the rotary type or the single blade type. It is also to be understood that the lamps may be set in any kind of sockets attached to either the front or the back of the board.

Obviously, all wiring is on the back of the board. The stripes connectin these lamps to their operative switches may also be painted other colors than above indicated so as to en' hance their contrast from the background of the board.

Having now fully described my invention and explained its use, I wish to be limited only by the claims.

I claim:
